Family Carangidae

Jacks

Jacks are compressed silvery fishes with a pair of dorsal and anal fins, stiff, forked tails and narrow caudal peduncles often protected by a hard ridge of scales known as scutes.  In most species the first three anal fin spines are embedded in the skin just behind the anusThese carnivorous fishes may form schools or aggregations and occupy a wide range of habitats including estuaries, bays, reefs, and the open sea.  Some species will hunt opportunistically by trailing other carnivores as they forage including eels, sharks, and marine mammals.  Jacks are valuable food and sport fishes but large individuals have been depleted in many areas.  Large Carangids feed heavily upon reef fish so caution is advised as diners run the risk of ciguatera poisoning.
